Agree. But in reality even 00 gauge wire will not dissipate the charge 
or handle the current from a direct lightning strike.
The 14 GA wire may, however, allow a light discharge to help prevent the 
build up of a much larger charge.

This is part of the reasoning behind lightning rods, i.e. dissipation of 
charge vs direction of a direct strike.
